4x5 in a Jobo 3005 drum?

[tim atherton]

Has anyone tried processing 4x5 film in a Jobo 3005 8x10 film drum...? (on a jobo processor)

Are the tube holes the same diameter but just shorter on the 3010 drum?

[Scott Davis]

The tube holes are a slightly different diameter, and lack the ridges for keeping two sheets separated during agitation. If you want to do 4x5 in an expert drum, get the 3010.

"If you want to do 4x5 in an expert drum, get the 3010."

which is why I asked... those puppies aren't exactly cheap and I have the 3005 already (I only paid 350.00 for my processor and the drum is about $276.00 - remember the definition of a Yorkshireman - a Scot who has had his free spending generosity removed...)

No reasonwhy you couldn't easily use it to process 5 sheets of 4x5 though.

I don't owna 3010 drum but I do own two 3060 drums and use them for both 5x7 and 4x5.

I own a 3010 and also a couple of those cheap unicolor 8x10 print drums. Often I end up using the print drums: I can do my washing in there (Ilford method) and use photoflo without a worry.

Tim,

I have both drum,but have neve tried what you're suggesting. I suspect that in solution the 4x5 film would twist and move around in the 8x10 drum and you would risk one corner scratching another part of the sheet. Even the 8x10 film moves around slightly, so the 4x5 would really move. I have developed 5x7 in the 8x10 drum and scratched the edge of some sheets.

Regards, Pete

Tim, greetings.

I've been using my 3005 to process ten 5x7 negatives at a time. You can do this by taping the long edges of two negatives together with Scotch tape on the base sides, thereby creating a single 10x7 piece that you then put into the tube as you would an 8x10 negative.

The only problem is that the antihalation dyes under the tape cannot wash off the base, so, when you pull the negatives from the tank and remove the tape, the negatives will have streaks of dye where the tape had been. But the dye will wash off in the rinse. I put my negatives in my print washer and let the water run 40-50 minutes, and that does the trick.

Be sure to keep a pair of print tongs handy. On rare occasion the tape will give way and leave the lower negative in the tube -- print tongs can be used to pull it out.

I have processed literally hundreds of 5x7 negatives in the 3005 this way and have gotten flawless results every time. I see no reason why you couldn't do the same with 4x5 negatives.

Best,

i have also processed 5 sheets in a 8x10 drum with good results, until business picks up i will hold off buying the 3010 4x5 drum although 10 sheets a whack is appealing.

best of luck

I have recently had good results with the 2800 drums and 8x10 and found that the little 2800 'test drum' holds 3 sheets of 4x5. Since I already have a 3010 Expert drum for the 4x5, I have only used the little 2800 drum once, but it worked well. I got that little drum basically free with some other 2800 drum pieces.
